  • 1.  Hard choice of remote drive as NFS

    My AIX 5.3L (p550) has 4 hd belonging to 2 groups (rootvg hdisk0 and hdisk1, appvg hdisk2 and hdisk3). Because I installed the Oracle 10g app on the hdisk1, its data stores in hdisk3, and hdisk2 has a BAAN v appl. On average, iostat shows
    Disks: % tm_act Kbps tps Kb_read Kb_wrtn
    hdisk3 1.7 189.2 4.0 194084478 28133680
    hdisk0 0.3 6.5 1.0 2106989 5488438
    hdisk2 0.3 129.0 0.9 8628882 142825548
    hdisk1 0.7 14.8 1.9 2113379 15313614
    Now I want to located a drive as a NFS remote drive for another AIX box, however the drive still has lots space are the hdisk1 and hdisk3. Because of the hdisk1 is part of the rootvg, while hdisk3 is the busy one, it is hard choice for me to use either one. Can anyone give me some considerations for the decision?

    Looking at the numbers, you probably want to put that on hdisk1. It's not
    a good idea to use hdisk3 where the Oracle datafiles are.

    It doesn't look like you have any performance problem at this point but you
    might want to consider adding more disks to the p550 when your budget allows.
